OIL-WELL BAILER.

Application filed May 11,

The present invention relates to a bailing device for use in connection with oil wells and provides a structure wherein it is possible to bail water from the well or place water in desired quantities in the well.

An important object of the invention resides in the provision of an improved structure as disclosed in Letters Patent No. 1,607,513 dated November 16, 1926.

Another very important object of the invention resides in the provision of an improved valve structure A still further important object of the invention lies in the provisionof a valve structure for a bailing device of this nature which is simple in its construction, easy to manipulate, thoroughly efficient and reliable in operation, and otherwise well adapted to the purpose for which it is designed.

\Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in cer tain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a vertical longitudinal section through a bailing device embodying the features of my invention,

Figure2 is an enlarged transverse section taken substantially on the line 22 of Figure 1,

Figure 3 is a perspective view of the valve structure,

Figure 4 is a transverse section taken substantially on the line 1-4 of Figure 1, c

Figure 5 is a transverse section taken substantially on the line 5 5 of Figure l, and

Figure (3 is a transverse section taken substantially on the line 6-6 of Figure 1.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes a cylinder having a valve structure V in the lower cnd thereof. s

A U-shaped handle 10 has its extremities riveted or otherwise fastened to the cylinder as at 11 so that the intermediate portion of the handle which is indicated specifically by the numeral 12 is disposed above the upper end of the cylinder in spaced relation thereto and transversely thereof. A guide tube 13 pierces an opening in the center of themtermediate portion 12 and has a nut 14 threaded on the upper end thereof above the portion 12. This nut has a flange 15 1927. Serial No. 190,616.

for engaging the portion 12. A substantially elliptical shaped cam 18 is threaded on the lower end of the guide tube 1.3. A pair of hell crank levers are indicated generally by the letters A, and each includes a short arm 19 and a long arm 20. The joint 21 between the arms 19 and is in the form of a fulcrum to be received in a suitable groove or recess 22 provided in the handle 10 at the juncture of the intermediate portion 12 with the side. The short arms 19 extend inwardly and terminate adjacent the guide tube 13. Catch projections 23 extend inwardly from the long arms 20 intermediate their ends. The free ends of the arms 20 move in slots 24 provided in a bar 25 extending transversely across the upper end of the cylinder 5, said bar being preferably attached to the sides of the handle 10 in any suitable manner such as is indicated at 26. A rod 27 .is slidable through the guide tube 13 and at its upper end is provided with a suitable clevis 28 in order that a cable or the like 29 may be attachedthereto. A coupling 30 is provided on the lower end of the rod 27 in order that a rod 31 may be attached thereto. The rod 31 is slidable through a central opening 32 in the bar 25. This bar 31 operates the valve mechanism as will be hereinafter more fully explained. A washer 35 is slidable on the tube 13. A spring 36 is coiled about the tube 13 and impingcs against the washer 35 and the elliptical cam 18 so that said washer 35 is i1npinged against the ends of the short arms 19 to maintain the long arms 20 in engagement with the cam 18. By turning the nut l t with a wrench, the tube 13 and the cam 18 may be likewise turned. By positioning the cam 18 longwise between the long arms 20, the catch projections 23 may be spaced su'iiiciently apart so not to be engaged by the coupling 30." However, by positioning the cam shortways, the catch projections 23 will be positioned sutliciently close together to be engaged bysaid coupling 30.

Attention is now directed to the structure of the valve V. The numeral denotes a cylindrical easing or housing for the valve structure and the upper end thereof is reduced as at 51 and telescoped in the lower end of the cylinder 5 and is riveted to the cylinder as at 52 or otherwise attached thereto. A stop ring 53 is mounted in the lower end of the housing or casing 50 by means of screws 54 or in any other suitable manner.

This housing or casing is provided with a plurality of longitudinally extending slots 55. The letter G denotes a cage structure which includes an annular member with a frusto-conical bore as at 56. A plurality of arms 57 rise from the annular member 55 and are connected at their upper ends by a spider 58 which is engaged with the lower end of the rod 31 by means of nuts 59-and 60 or in any other suitable manner. A ball (31 is mountable in the cage G and seatable on the upper end of the frusto-conical bore 5b for closing the same. A plurality of members (33 are engaged on the annular member 55' to slide in the slots 55 to prevent the cage structure from turning.

The upper edge of the annular member 55 is beveled as at (a to seat in an annular head projecting inwardly from the upper portion of the cylindrical housing 50. When the parts are disposed as is shown in Figure 1 and the bailing device is let down in a well it will be seen that when the housing 50 strikes the bottom of the well the cage structure G will open and the water or like fluid may flow in through the slots 55 to till the cylinder 5. As the cable 529 is lifted it will first cause the lifting of the cage structure until the annular member 55 closes against bead seat 65 and then the whole bailing device will be lifted up with thefluid contents therein. If it is desired to place the water or other fluid in the Well, the cam 18 is turned to be shortwise between the arms 20 as heretofore indicated and at this time the coupling 30 will be above the projection 23 and the annular member 55 will be seated on the valve forming head 65 so that fluid may be forced into the cylinder and let down into the well. When the housing 50 strikes the bottom of the well it will be seen that the cag elike structure will move downwardly to unseat the annular member 55 and the coupling 30 will engage with the projections 23 so that said cage structure cannot be moved upwardly as the device is withdrawn from the well. Thus all oi the contents of the bailing device will be left in the well. An important feature of this improvement is that as soon as the bailing device when filled in the last mentioned example reaches the water the ball 61 is unscated and thus the fluid in the bail may be thoroughly mixed with the fluid of the well during the further lowering of the bailing device. This is not possible with the patented structure heretofore referred to. V

It is thought that the construction, operation, and advantages of this invention will now bequite apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the in vention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without 'departii'ig f-ronirthe spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
